If you have narrowed your shortlist to two specific designs, this is exactly the kind of decision where a side-by-side spec view saves a weekend of second-guessing. Both plans below are complete, code-aware DIY builds, but they differ on the things that matter for a backyard project — total cost, raw labor hours, footprint, and the wood species on the cut list.

Cost & budget
The 20x20 ft 5-Point Overlapping Shade Sail Frame Plan lands in the $5,375–$8,400 range for materials in Cypress, while the 20x20 ft Sail-and-Rafter Hybrid Shade Sail Frame Plan runs $5,150–$8,075 in Western Red Cedar. The second plan is approximately 4% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of Cypress over Western Red Cedar and the difference in cubic concrete volume between 4 and 4 footings.
Labor & difficulty
At ~14 hours, the 20x20 ft 5-Point Overlapping Shade Sail Frame Plan is rated Beginner. The 20x20 ft Sail-and-Rafter Hybrid Shade Sail Frame Plan takes ~24 hours and is rated Beginner. The labor delta is roughly 10 hours, or one extra working day on the 20x20 ft Sail-and-Rafter Hybrid Shade Sail Frame Plan. Both plans require the same skill level, so the deciding factor is footprint and aesthetics rather than your comfort with carpentry.
Footprint & site fit
At 400 sq ft vs 400 sq ft, you are choosing between a full outdoor room and a full outdoor room. Allow at least 24 inches of clearance on every side for furniture and walking paths — that means the 20x20 ft 5-Point Overlapping Shade Sail Frame Plan needs a clear area of approximately 24×24 ft and the 20x20 ft Sail-and-Rafter Hybrid Shade Sail Frame Plan needs 24×24 ft.
Material & durability
The 20x20 ft 5-Point Overlapping Shade Sail Frame Plan is built from Cypress, while the 20x20 ft Sail-and-Rafter Hybrid Shade Sail Frame Plan calls for Western Red Cedar. The species choice drives the cost delta and the maintenance schedule. Pressure-treated southern yellow pine is the cheapest and most rot-tolerant for in-ground posts; western red cedar is the DIY favorite for visible parts; redwood and white oak are heritage choices that command a premium.
Verdict
For a builder weighing these two specifically, 20x20 ft 5-Point Overlapping Shade Sail Frame Plan is the faster build. If both fit your budget and yard, default to the design whose style language matches the rest of your house — a Craftsman bungalow looks awkward beside a modern slatted pergola, and vice versa.
